The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.

This collection contains web crawls performed as the pre-inauguration crawl for part of the End of Term Web Archive, a collaborative project that aims to preserve the U.S. federal government web presence at each change of administration. Content includes publicly-accessible government websites hosted on .gov, .mil, and relevant non-.gov domains, as well as government social media materials. The web archiving was performed in the Fall and Winter of 2016 to capture websites prior to the January 20, 2017 inauguration. For more information, see http://eotarchive.cdlib.org/.

Welcome to the Propulsion Systems Analysis Branch at NASA Glenn Research Center in
Cleveland, Ohio. Here, we strategically assess this
center’s aeronautics activities.
We play a critical role in analytically calculating the performance
and economic benefits of advanced and unconventional propulsion and
related systems. These assessments help to influence NASA’s
decision-making process and strategically guide the direction of its technology
technologies developed under these programs enable the Agency
to charter a bold new course by improving the quality of life
on this planet and exploring the universe.
We are committed to revolutionizing propulsion
technologies to ensure the U.S. industry’s
global preeminence in both aeronautics and space. These technologies
will lead to environmentally friendly, safe and economically viable
air transportation, improve our understanding of the universe,
and enable human and robotic exploration of the solar system.
We are excited to be part of the technological journey into
the new century and invite you to join us in this great adventure
by learning more about what we do, how it affects you, and
how you can play a role.
